#em12c Metrics – Part 3: Breakdown of Metrics using Repository Views

With my previous post on the “All Metrics” page breakdown in Enterprise Manager I talked about the collected, aggregated, and available information on metrics for a given Target type. As we’ve seen, the Metrics Categories are numerous and really depend on the monitored targets. Well, what does that mean? And, how does one find out […]

#em12c Metrics – Part 2: Breakdown of the “All Metrics” GUI Interface

In my previous post on #em12c Metrics: An Introduction, I wrote briefly on the basics of Enterprise Managers collected metrics, their various location(s) within the Oracle Manager Repository and shared a few queries on how to retrieve and view the data. Today, I’d like to resume the series and explain how the Metrics are accessible […]

An Implementation of GoldenGate Monitoring configured in a Real Application Cluster Environment

Nearly a year ago I wrote about GoldenGate monitoring using a Metric Extension, and then later on expanded upon the creation of a Metric Extension, which I’ve installed and configured at several customer sites where GoldenGate was running on a stand alone server. Over the last few months, several people had approached me on the process, […]

Migrate Enterprise Manager 12.1.0.4.0 to a PDB from a non-CDB

One of the things I’ve been eager to try with the latest (12.1.0.4.0) EM release was to change the repository from a non-CDB to a PDB. There’s a note in the EM documentation that discusses migrating the SYSMAN schema option mentioned here. As a mentionable note, Martin Bach wrote a post on switching the repository […]

Enterprise Manager 12.1.0.4.0 – Post Upgrade Tasks

With the new release of Enterprise Manager, I upgraded my 12.1.0.3.0 installation successfully using the superb documentation here. It is however, important to note that the post-steps are also important. For example, upgrading (at the very least) the Management Agent on the OMS host, and de-installation of the old-OMS home. Gokhan Atil wrote a good […]

Inherited Problems on an #EM12c with Admin Server Woes

Today, I had the pleasure of deploying a couple of plugins for Application Management Pack (eBusiness Suite and Siebel) when I came across a nasty error during the actual deployment phase where the OMS is shutdown and restarted. Umm, what the %#$@? When I checked the emctl.log, it seemed to me that the deployment process had […]

Patch and Provision in EM12c: #5 Provision a Real Application Cluster Database

As part of the Database Lifecycle Management (DBLM) Pack, Database Provisioning in Enterprise Manager is a powerful and quite flexible feature to provision databases. In the past, I have written several articles on Patching and Provisioning (P&P) using the #em12c and today I’d like to add one more to the list. This time, it is […]

Metric Extensions in EM12c #1: Monitor a Useful Target such as a GoldenGate Instance

Back in August of 2013, I wrote a post on “Alternative Method to monitor GoldenGate from EM12c outside the GoldenGate 12.1.0.1.0 Plugin” and then back in December of 2013 I wrote another one a Metric Extension to Monitor Unsupported Database Versions. As it turns out, the first post has been quite useful in many customer […]

Create a Standby Database using EM12c

I wanted to make this a quick post, because a friend was mentioning a slight problem during a manual set up of Data Guard. I told him you could do it through EM, and then recalled that I had documented it a while back. After the tube light finally went on in my head, it […]

#em12c Metrics – Part 1: An Introduction

From the middle of 2013, I’d been busy in preparation for one of my presentations for IOUG’s Collaborate 14 Conference in Las Vegas. It is on Capacity Planning Enterprise Manager 12c’s Metrics (available on slideshare), one which I had the honor of presenting earlier at a Georgia Oracle User Group meeting in Atlanta, GA this […]

Things I see and learn!

Thoughts from James H. Lui

If you Care a Little More, Things Happen. Bees can be dangerous. Always wear protective clothing when approaching or dealing with bees. Do not approach or handle bees without proper instruction and training.
